Question

Plants that flower only once are
A) Pericarpic
B) Monocarpic
C) Polycarpic
D) Cliestocarpic

Answer 1

A.G. Tansley, an English botanist, coined the term "ecosystem" in 1935. An ecosystem's structure is defined by the organisation of both biotic and abiotic components. This includes energy distribution in our environment. It also includes the prevailing climatic conditions in that particular environment.

Complete answer:
Plants that bloom have a distinct life cycle.
- Seed: They start out in life as seeds. Seeds are the offspring of plants. The seed embryo within is protected by a strong outer shell.
- Germination: The seed germinates and falls to the ground. To rise, requires air, water, and soil. Germination is the process by which a seed starts to develop. The first signs of life are normally some small roots. The stems will then begin to grow.
- Sprout or seedling: A sprout or seedling is the first sign of life that occurs above the soil.
- Mature plants: Plant with leaves, roots, and stems - The seedling will develop into a completely mature plant with leaves, roots, and stems.
- Flowering: As the plant matures, it will produce flowers. The flowers can release seeds as a result of pollination. The cycle will begin again when the seeds fall to the ground.

The pericarp, which originates from the ovary wall of the flower and surrounds the seed to protect it in surroundings other than the parent plant, is the outer covering (usually edible) of fleshy fruits.

Plants that blossom and set seeds multiple times before dying are known as polycarpic. Polycarpic plants can reproduce several times because at least some of their meristems can sustain a vegetative state in some way, allowing them to reproduce again.

A cleistocarpous moss (rather than a cleistocarpic moss) has capsules that do not open to release the spores inside. The spores are only distributed when the moss and its capsules have decayed (over, of course, a relatively short distance). A well-known example is Phascum cuspidatum (Toothed phascum moss).

Monocarpic plants are flowering plants that only grow flowers and seeds once in their lives. The majority of Monocarpic plants are annuals. Annual plants complete their life cycle in a single season, from seeds to flowers to seeds. An annual plant's roots, leaves, and stems die after one year. The dormant seeds are what cross the gap from one generation to the next.

Rice, carrots, bamboo, maize, bromeliads, sunflowers, tillandsias, radishes, lettuce, bananas, zinnias, palms, agaves, aeoniums, and annual flowers are examples of Monocarpic plants.

Before flowering once and dying, all monocarpic perennials spend more than a year in a vegetative stage. Herbs and shrubs make up the majority of monocarpic perennials. From strictly biennials to long-lived monocarpic perennials, the length of the vegetative cycle varies greatly between plant species. The population dynamics of this group of plants are heavily reliant on environmental signals that decide flowering, which in turn causes reproductive individuals to die.

Plants that flower and set seeds several times before dying are known as polycarpic. Pleonanthic and iteroparous are words that have the same meaning. Polycarpic plants can replicate several times and at least some of their meristems can sustain a vegetative state in some way, allowing them to reproduce again.

The correct answer is option (B) i.e, Monocarpic.

Note: We know that the flowers are the reproductive parts of a plant. Stamens are the male reproductive part and pistil is the female reproductive part. The gynoecium represents the female reproductive part of the flower in monocarpic fruits. The gynoecium can have a single pistil (monocarpellary) or multiple pistils (multicarpellary).
